Handover method in wireless telecommunication system supporting USTS
First Claim
1. A method for performing a handover of a mobile station in an asynchronous wireless telecommunication system supporting an uplink synchronous transmission scheme (USTS) mode, comprising the steps of:
- a) performing a mode conversion of the mobile station from the USTS mode to a non-USTS mode based on a first signal measurement result from the mobile station; and
b) performing a handover for the mobile station.

Abstract
A handover method in wireless telecommunication system supporting USTS is disclosed. The method for performing a handover of a mobile station in an asynchronous wireless telecommunication system supporting an uplink synchronous transmission scheme (USTS) mode, includes the steps of: a) performing a mode conversion of the mobile station from the USTS mode to a non-USTS mode based on a first signal measurement result from the mobile station; and b) performing a handover for the mobile station. In another embodiment of the present invention, the method further includes the step of: c) performing a mode conversion from the non-USTS mode to the USTS mode based on a second signal measurement result from the mobile station.
